My code doesn't work, but it reads correctly to me. What did I do wrong?

var id = "23188xtr"; var lastName = "Smith"; id.toUpperCase(); var userName lastName.toUpperCase(); userName += id + +"'#'+ lastName;

app.js 
var id = "23188xtr";
var lastName = "Smith";
id.toUpperCase();
var userName
lastName.toUpperCase();
userName += id + +"'#'+ lastName;

var id = "23188xtr";
var lastName = "Smith";
id.toUpperCase();
var userName
lastName.toUpperCase();
userName += id + +'#'+ lastName; // Took  out the one double quote before the hash

var id = "23188xtr"; var lastName = "Smith"; id.toUpperCase(); var userName; userName += id + +'#'+ lastName;

That additional quote shouldn't have even been there, but the problem remains. It still won't read this as a concatenation so I don't know what it expects me to do?

There's also an extra + in that last line.

userName += id + '#' + lastName; // removed an extra +
